Relevant personnel from the company's technology center observed the top-push construction of the Huazhuanghe steel box girder.

　　Recently, the company's technology center participated in the Huajiang River steel box girder launching learning and exchange activities organized by the group company.

　　The steel box girder launching operation is for the construction of the Huazhuang River Bridge section of the Diazhong Industrial Cluster Area (New Area) Shaoguan Road project. This launching is for the sixth section of the right-side auxiliary road bridge, with a total length of 96.551m, a bridge weight of 637.24t, a guide beam weight of 78.5t, and a launching distance of 48m. This steel box girder launching has construction characteristics such as cross-river construction, large span, high height, and a downward sloping ramp for the bridge body. The launching uses a temporary slide support device, prefabricated assembly, segmented launching, and a top-down unidirectional sliding launching method, a single-point step-by-step launching method.

　　Through on-site exchange and learning, the observation group has a deeper understanding of the practical application of "bridge launching construction technology" in the project, providing a good reference for the company's bridge launching construction work, and also providing technical preparation for the company's Ninth Engineering Project Department's Huaping-Lijiang Expressway Seventh Contract Ramp steel box girder launching construction.
